Obama Circle of Trust: Aniston In, Stiller Out

GOT HER BARACK Aniston, Obama (inset)

Jennifer Aniston's star may have fallen a bit in recent months—news about her rhinoplasty dominated headlines, and her revenge relationship with Vince Vaughn fell apart—but she worked the diva angle at last night's fundraiser for Barack Obama, hosted by Hollywood's power troika of Steven Spielberg, David Geffen, and Jeffrey Katzenberg.

When guests entered the ballroom at the Beverly Hilton, everyone was given a name tag—even bold-faced names like Aniston, Ben Stiller, Eddie Murphy, Zach Braff, Ron Howard, and Morgan Freeman.

"Jennifer wasn't having it," says a partygoer. "She didn't want to wear it—she took it off right away."
